ENDOSCOPIC INTERMUSCULAR DISSECTION FOR THE LOCAL RESECTION OF RECTAL CANCER

Video Transcription

Video Summary

This video showcases the technique of endoscopic intramuscular dissection for the local resection of rectal cancer. It discusses the benefits of local excision for rectal lesions with deep submucosal invasion, as it allows for organ preservation in patients. The video provides a step-by-step description of the procedure, including submucosal marking, injection of lifting solution, mucosal incision, and intramuscular dissection. The resected specimen is inspected, confirming negative margins. Endoscopic intramuscular dissection offers advantages over other excision procedures, such as en bloc specimen retrieval without disrupting the total mesorectal excision plane. Further research is needed to determine optimal indications and potential adjuvant therapies for this technique.
